In "Presence," Harvard psychologist Amy Cuddy reveals how body language transforms confidence. Her second-most-viewed TED Talk (62M+ views) inspired scenes in "Ted Lasso" and "Grey's Anatomy." Can two minutes of power posing really change your life? Half a million readers think so.
Amy Joy Casselberry Cuddy, social psychologist and New York Times bestselling author of Presence: Bringing Your Boldest Self to Your Biggest Challenges, is renowned for her groundbreaking research on body language, power dynamics, and personal transformation. A Princeton PhD and former Harvard Business School professor, Cuddy bridges academic rigor with practical insights in this self-help classic about overcoming self-doubt through embodied confidence.
Her viral 2012 TED Talk on "power posing" – watched over 74 million times – laid the foundation for the book’s science-backed strategies to cultivate authenticity in high-stakes situations. Cuddy’s work has been featured in The Wall Street Journal, Time, and NPR, and she’s advised organizations from Google to the World Economic Forum.
Her upcoming book Bullied (2025) expands her exploration of psychological resilience. A traumatic brain injury survivor turned award-winning researcher, Cuddy brings firsthand understanding of overcoming adversity. Presence has sold over 500,000 copies worldwide and been translated into 35 languages, cementing its status as a modern personal development staple.
Presence explores how to cultivate confidence by aligning actions with authentic self-expression, even under stress. Amy Cuddy combines psychology research and personal anecdotes to argue that body language (like "power posing") and mental focus can reduce anxiety and combat imposter syndrome. Key themes include overcoming self-doubt, harnessing personal power, and projecting credibility in high-pressure situations.
Professionals, students, or anyone facing self-doubt in high-stakes scenarios (e.g., job interviews, public speaking) will benefit. The book offers actionable strategies for improving confidence, making it ideal for readers interested in psychology, leadership, or personal development. Cuddy’s blend of science and storytelling appeals to both academic and general audiences.
Yes, particularly for its evidence-based approach to building confidence. Cuddy’s insights on body language’s impact on mindset and her "power posing" technique have resonated globally. Critics note debates over some research validity, but the book remains influential for its practical advice on authenticity under pressure.
Power posing involves holding open, expansive postures (e.g., standing tall with hands on hips) for 2 minutes to increase testosterone and reduce cortisol. Cuddy’s research suggests this "fake it till you become it" method fosters confidence, popularized in her TED Talk with over 74 million views.
The i-Posture describes how using small devices (e.g., phones) causes slumped postures, reducing assertiveness. Cuddy’s experiments found subjects using smaller screens acted less confidently. She advises countering this by maintaining upright posture during tech use.
Yes. Cuddy emphasizes aligning body language with speech to project authenticity. Techniques like power posing pre-presentation and focusing on self-trust (not audience judgment) help speakers feel calmer and more compelling.
Yes. Cuddy draws on her social psychology research to explain how nonverbal cues (posture, gestures, eye contact) influence others’ perceptions and one’s own mental state. The book details studies linking expansive postures to increased confidence and risk-taking.
Some scientists question the replicability of power posing’s effects, though Cuddy maintains its value as a tool for self-affirmation. Critics argue the book oversimplifies complex psychology but praise its accessibility for non-academic readers.
Yes, including:
Cuddy describes it as a momentary state where actions, speech, and emotions align with core values. It’s marked by reduced self-monitoring and greater trust in one’s abilities, enabling genuine connection with others.
The book advises using body language and mindset shifts to project leadership potential during networking, negotiations, or promotions. By reducing anxiety-driven behaviors, individuals can advocate for themselves more effectively.

Think about the last time you bombed an interview, froze during a presentation, or went completely blank when someone asked what you do. Your palms sweat. Your voice cracks. Your mind races through every possible way you're failing in real time. Now here's the twist: what if the solution wasn't in your head at all, but in how you were standing? After a car accident dropped her IQ by thirty points and derailed her academic dreams, a young researcher discovered something revolutionary-our bodies don't just carry our emotions, they create them. This insight, backed by rigorous science and watched by over 50 million people, reveals that personal power isn't about changing who you are. It's about changing how you hold yourself long enough to remember who you've always been. Presence is maddeningly difficult to define yet instantly recognizable. Picture someone who walks into a room and somehow shifts the energy without saying a word. It's not their resume or credentials-it's something else entirely. When entrepreneurs pitch ideas with genuine enthusiasm, they don't just communicate information; they signal drive, persistence, and creativity. This quality becomes contagious, stimulating commitment in everyone around them. The beautiful paradox? Presence isn't some mystical state requiring years of meditation. It's far more accessible: being attuned to and comfortably expressing your true thoughts, feelings, and values in the moment.
